No, you didn’t miss a contest here. (Sunday night. New BlizzCon ticket contests go live Monday morning.) This is a contest that was held this summer on the Colors site. There were 3 winners and quite a few entries, all of which . The cool thing is the application used to create these images. To quote the site’s :
Colors! is a simplistic digital painting application for Nintendo DS that is inspired by painting-techniques using Wacom boards in Photoshop or Painter.
Thanks triplex for the tip!
